HEDbLE- FRAME.

SPECIFICATION forming part of Letters Patent No. 585,830, dated July 6, 1897. Application filed February 1, 1897. Serial No. 621,404. (No model.)

To all whom it may concern.

Be it known that I, CHARLES H. NIEDNER, a citizen ofthe United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which a full, clear, and exact description.

This invention relates particularly to looms which are designed for weaving linen fire hose; and the special improvements which I have devised are in the line of, certain details hereinafter set forth.

In weaving fire-hose it is necessary to employ so large a number of warp-threads in order to make the hose sufficiently heavy and impervious that eight harness-frames have usually been used. This of course requires an equal number of harness-actuating cams and other operative mechanisms and adds loom. The reason why so large a number of harness-frames is required is because a lesser number would pack the heddles so thickly in addition subject the same to undue wear.

In the course of my experiments I discov- I could not double the number of heddlesin the same vertical plane in each harness-frame, yet by so-arranging said frames that they could each carry two sets of heddles iuseparate planes, one directly behind the other, I could supply my loom with all the warpt-hrcads necessary and still diminish the number of harness-frames to fQur, oi',,oi1e-l1alf of what were usually 'eiiiployed. After further experiment I succeeded in constructing the duplex harness, which forms the main subject-matter of this application.

In the drawings forming part of this specification, Figure l is a perspective view of a loom provided with myimprovements. Figs. 2, 3, and 4 are detail views of my harnessframe.

Referring to Fig. 1., A A A A are the harness-f'rames, actuated by the cams M, acting chains I. L, and suitable sheaves If.

II represents the woven portion or completed hose passing downward over the stand g. Over this stand g is bolted a bridge E, spanning the completed hose. To this bridge is secured the guide F.

In Fig. 2 is shown my duplex harness-frame complete, while'in Figs. 3 and 4 are given sectional and perspective views of parts thereof upon a larger scale. In making this frame the top A and also the bottom A are each composed of two thin strips of metal a and a. These strips are separated one f rom theother a space about equal to their own thickness. The sides A are also each formed from strips of metal, but five in number, a a (t a a.

Three of said strips a a and a receive between their ends .the strips a a, composing the top and bottom, and by means" of rivets or other fastenings form inflexible joints at such points.' Two of the strips of a in each side A are shorter than their fellows, form-- ing thereby the openings b b At the center of the frame top and bottom A A are the two blocks b having the eyes Z) Z)- in line These blocks are secured in position by being provided with a strips a a.

attached to wires 0 havin 100 )s c at their ends, through which loops pass the rods Z) N. Said rods are prevented from accidental removal by means of the cotter-pins 7), inserted therein and bearing against the frame sides.

As will be readily seen, this arrangement permits of the employment of two sets of heddles in each harness-frame, one set being in a plane immediately as previously stated, enables double the number of warp-threads tobe carried byeach frame.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is as follows, to wit:

'In a loom, the lun'ncss-frame comppscd of the top and bottom, A, A cach'form ed ol. two. thin strips, (1, a, the sides, A, each behind the other, and,
